To all whom it may concern:

Be itknown that we, Bnrzxinn J. Down and Axrrrosr U'rz, residing in Hartford, 1n the county of Hartford and State of Connecticut, citizens of the United States of America, have jointly invented a ccrtam new and useful Carriage-Support for Type- Writing Machines, of which the following is a specification The object of this invention Is to provlde an outlying support for the carnage of typewriting machines, that is a support located beyond each side of the back central support of the carriage to more stemfhlg hold ext 'a long carriages and prevent tilting when m extreme overhang lateral PIBItIOnS The invention, as adapted be appl ed to the Royal typewriting machine, compnsrs a guide rod at the extreme rearward part of the carriage by suitable brackets to the lower gn-ide-wayand beanng rollers carried by a hair the length of the carriage at'iis rear, as the tabular rack, and

to act on the top of this flnrd hearing rail and supports for the at inchslde of the. central sup- 4 rod of the riage; ;aiord supports prevent i cfestr ag w 1S Outer or overhang Referring n o' t momrmr r ings to more fnllfdtscn'be the nvention: Figure 1 is aireer eleration of theports of; machine to which the third beanngrod is attached and which it enacts. Fig. 2, a plan view of the-same; F .3, q transverse sedion on an M Fig. 4 shows one of the bearing rollers its connection to the tabular rack;,Fig. 5 is a plan view of one of the third hearing rod connections and its supporting bracket; and Fig. 6 is a rear elevation of the same.

Asshoxvnkigathe drawmglsagthe ports 6X15;- inthe y machme' eons i s l: of the:1 end frasmes 7 of the cggfiagle, the Iower e-way rocklng' arm an parallel 10 for operetin end the shift frame to which e. ghideway 81's afiached, platen 11, part of the mom frame 12, tabular rack 13 secured toand extending between the frames 7, the 14 alsosecured tothe frames? andtherod controlling rollers 15 on ehracket 16 55 extending rearwardly from the carriage shift frame. The third carriage bearing is shown as a rod 17 at the rearward part of the machine extending somewhat in lateral directions beyond the lower ball bearing guide-way 8. It is carried on two bracket arms 18 secured by screws 19 to and projecting rearwardly from the lower guide it ay 8. The ends of these arms are vertically faced, and double angle plata 20 are secured to these faces by screws 21, the holes in the plates being vertically elongated to provide for their vertical adjustment. The guide rod 17 has slots or grooves iormed in its front side into which fit the ends of the top angle parts of the plates 20, they being securel i fastened together by any suitable means. The bottom angle parts 22 of plates 20 extend under the ends of the arms 18, and through them pass screws 23 provided with lock nuts and whose ends butt against the underside of the arms. By these means the rod 17 is set accurately and parallel with the lower ball bearing and guide rod 14 of the carriage and, when set, is securely held by the screws 21.

Depending from the tabular rack 13 are hookshaped guards and roller carriers 2-1, the. hooked of which extend around the 1-061? ends a short distance from the undersides of the parts of the angle plates 20 that are secured to said rod. This allows the guards 24, which, of cow's, move with the carriage, to pa by the angle plates 20 Without hindrance. To the vertical portions of the guards 24 are attached rollers 25 fitted to rotate on screw studs 26, the rollers being located to rest on the top-side of the guide supporting rod 17, as shown at Fig. 1; and, with the carriage in central position on its uide theserollers 25 are a oonsh erable distance from each side of a central line on which the rollers 15 of the hearing rod 14 are loeated. This construction and arrangement of parts, as will be observed in Fig. 2 (in which the dotted circles 27 represent the end bearing halls of the carriage front bearing) provides a. very extended base of support for the carriage far in excess of such base with, the carria provided with front ball beat-in and r 14 and rollers 15 rear bearin only.

%he guard and roller carriers 2-! are secared to the tabular rack 13 by their upper ends 28 having segments of circles formed carried an aepw 1 71;

thereon and seatedin corresponding grooves or slots formed in the underside of tabular rack 13, and screws 29 fitted in the rack adjacent the ends of the grooves with their heads bearing against the lmdersides of the segments, as seen in Fig. 4. The guards 24 are securely famned to the rack, and they may be adjusted on the rack by manipulating the screws The bracket arms 18 have lateral lugs 30 projecting toward the center of the machine, and through these lugs are vertically fitted screws 31 provided with lock nuts and arrangedtorestonthebodyormain fmme 12. These screws act as stops for the low position of the shift frame and carriage amL by reason of their position and p oper adjustment, the rear part of the carriage is rigidly supported and the platen steadily held against all vibration and rocking mo tion in lower case printing.

The bearing bar 17 and its enacting parts are shown applied as an auxiliary bearing to a machine having a bearing bar 14 on the carriage and held between the end frames. The bar 1'2 may be used as'the sole means for supporting the rear part of the carriage in the manner described and it will efiectnall do so,the base of the bearing support of the being more extended than that due tothe use of the b51- 14.
